Description

Positioning structure of groove type embedded part in side wall of cast-in-situ underground comprehensive pipe rack Technical Field The utility model relates to the technical field of cast-in-situ underground comprehensive pipe racks, in particular to a positioning structure of a groove type embedded part in the side wall of a cast-in-situ underground comprehensive pipe rack. Background In the underground comprehensive pipe rack for intensively laying pipelines such as electric power, communication, water supply and drainage, heating power, fuel gas and the like, the embedded groove type embedded parts in the concrete pipe rack are supported by the high bearing capacity requirements of various pipelines, the groove type embedded parts are poured in concrete, and the embedded parts are required to be accurately positioned before the concrete is poured, so that the normal supporting function can be exerted. The existing positioning construction method for the groove type embedded part comprises the steps of connecting a groove type embedded part with a wood plate in a positioning mode after binding of the steel bars poured by the concrete of the underground comprehensive pipe gallery is completed, supporting a template and pouring concrete after connection is completed, wherein multiple positioning can not be performed on the groove type embedded part, unstable conditions can occur under long-time use only by means of a single bolt and a mode of connecting the single bolt with the steel bars, and accordingly the operation of the cast-in-situ underground comprehensive pipe gallery can be influenced in actual use. Disclosure of utility model The utility model aims to provide a positioning structure of a groove type embedded part in the side wall of a cast-in-situ underground comprehensive pipe rack, which aims to solve at least any one of the problems in the prior art. In order to achieve the above purpose, the positioning structure of the groove type embedded part in the side wall of the cast-in-situ underground comprehensive pipe rack comprises an embedded part body, wherein riveting rods are fixedly connected to two sides of the bottom of the embedded part body, four first threaded holes are formed in the bottom of the embedded part body, a first positioning assembly is arranged at the bottom of the embedded part body, and a second positioning assembly is arranged at the bottom of the first positioning assembly.
